Abstract

本实用新型公开了一种用于胸腔穿刺的可控深度的穿刺针,其特征在于:由带刻度穿刺针针杆(1)、可滑动套管组件(2)组成。穿刺针的针杆(1)上设有标准刻度,针杆上套有一个可滑动套管组件(2),可滑动套管组件(2)由套管(5)、固定簧片(4)、扳手(3)组成,由于穿刺针杆上带有刻度及可滑动套管组件,穿刺深度可以方便固定,使穿刺深度易于掌握,避免伤及肺组织,操作简便且安全。

Description

一种可控深度的穿刺针
技术领域  本实用新型属于医疗器械领域,特别适用于胸腔积液穿刺诊断治疗的一种器械。
背景技术  目前国内用于胸腔积液穿刺诊断治疗的穿刺针,由于没有刻度及固定器,穿刺深度不易控制,易伤及肺组织。
发明内容  本实用新型的目的就是克服上述缺点,提供一种能够掌握穿刺深度的专用穿刺针。
本实用新型的技术方案是:在普通穿刺针的基础上进行改进,即在普通胸腔穿刺针的针杆上增设刻度及可滑动套管组件。可滑动套管组件由套管、固定簧片、板手组成。
由于穿刺针杆上带有刻度及可滑动套管组件,穿刺深度可以方便固定,使穿刺深度易于掌握,避免伤及肺组织。
附图说明  图1是本实用新型的结构示意图
          图2是本实用新型可滑动组件的结构示意图
具体实施方式  本实用新型由带刻度穿刺针针杆(1)、可滑动套管(2)组件组成。可滑动套管组件由套管(5)、固定簧片(4)、板手(3)组成。穿刺针的针杆(1)上设有标准刻度,针杆上套有一个可滑动套管组件(2)。使用时,先确定好插入病变部位的深度,然后移动可滑动套管,移到所需的深度,按下板手,将可滑动套管固定,然后将穿刺针插入病变部位,抽取积液,操作既简便,又安全。
